BOTTLE-MAKING ZMACI'IINE.

To all whom it may concern:

Be it known that I, JULIAN H. KENDIG, a citizen of the United States, residing at Pittsburgh, county of Allegheny, and State of Pennsylvania, have invented certain new and useful Improvements in Bottle-Makmg Machines, of which the following is a specification. v

This invention has reference to machines for making glass bottles and the like and it has for its primary object the provision of an improved machine of the semi-automatic type together with an improved arrangement of operating means therefor whereby the machine is more effective and consistent in its operation. My invention also contemplates the provision in a fluid actuated semiautomatic bottle making machine, of an improved arrangement of valvular devices for controlling the various operative movements of the parts and the provision of improved means for actuating the valves. The foregoing, together With such other objects as may hereinafter appear or are incident to my invention, I attain by means of a construction which I have illus trated in preferred form in the accompanying drawings, Wherein Figure 1 is a side elevation of a bottle making machine embodying my improved features; Fig. 2 is an end elevation of the machine shown in Fig. 1; Fig. 3 is a plan View of Fig. 1; Figs. -1- and 5 are diagrammatic illustrations of different operative positions of the valve and operating mechanism.

Referring to the drawings, it Will be seen that I have illustrated only the blank forming table of a bottle making machine with my improvements applied thereto, though of course it will be understood that my invention is applicable to other machines of similar type. The machine com,- prises the usual framework or platform 7 having a centrally located standard or column 8 on which is rotatably mounted a blank or mold table 9 carrying in the particular embodiment shown four blank molds 10 suitably spaced apart. Mounted above the table 9 in position to aline with the blank mold is a blank-forming plunger 11 carried by the piston 12 mounted in the cylinder 13 which is supported by the columns 14 and 15. Mounted on the column 15 is a cylinder 16 which operates the shears 17.

The table is given a rotary step-by-step Specification of Letters Patent.

movement so as to bring a pair of molds, one in position beneath the blank-forming plunger 11, and the other beneath the shears 1. The mechanism for imparting this movement to the table Will noW be described. Suitably supported on a frame 18 ad acent the standard 8 is a horizontall d sposed cylinder 19 in which is mounted a piston 20 to which is secured a counter slide rod 21 by means of the connecting plates The piston rod 20 extends beyond either end of the cylinder 19, and the slide rod 21, which is of substantially equal length, is supported intermediate its ends by the guide plates 23 secured to the ends of the cylinder. Rotatably mounted on the standard 8 is a collar 24 held in the bearing shoulder 25 formed on the standard 8 and provided with a projecting arm 26. The arm 26 is connected to a plug 27 on the slide rod 21 by means of thelink 28. The arm 26 is provided with a springactuated pawl 29 which ratchets over inclined face blocks 29 (Fig. 3) on the under side of the table. From the foregoing it will be apparent that as the piston rod 20 and slide rod 21 are reciprocated, the collar 24 will. be given a rotary movement back and forth, and that the table will be ad-' vanced or rotated a step during the for ward movement, and will remain stationary during the rearward movement of the iston rod 20. The apparatus thus far described is of the usual character.

teferring now to the arrangement of piping for supplying pressure to the cylinders 13, 16 mechanism for controlling such flow, attention is directed to Figs. 1,3, 4 and 5. The movement of the plunger piston 12 is controlled by means of what shall be termed the plunger control valve 30, which valve is mounted on the bracket 31 carried on the framework 7. The valve 30 is of the slide valve type and is provided vvith'a plug 32 and also With three port openings, 33, 34 and 35, the port 34 being intermediate the ports 33 and 35, and being an exhaust port. A pipe 36 connects one end of the plunger cylinder 13 to the port 33, and-a pipe 37 connects the other end of the plunger cylinder to the port 35. From inspection of Fig; it it will be seen that in one position the port 33 is uncovered and the port 35 connected With-the exhaust port 34, and that position by Patented Mar. 23, 1915.

and 19, and also to the valvular.

in the oth r position, the port 35 will be uncovered and the port connected with the exhaust port -lel. Mounted in the plug and projecting beyond either end of the casing of the valve 30 is a rod 38. The rod 58 can'ies a framework comprising two end rods and a side rod l parallel to the rod 38. tine rod is located on each side of the val\. e The purpose of this frame: work will be hereinafter set forth. Secured to the forward end of the rod 38 is a cross bar ll. fit the rear end of the piston rod is an abutment 42 which is adapted to take against the rods and more the plug On the rearward movement of the piston rod the plug is moved to the position indicated in while on the forward nioven'ient of the piston rod 20, the plug 8:3 is moved forward, covering the port and establishing communication between the port and the exhaust port Located adjacent the plunger control valve 80 are two valves a3 and 4L4: which control the supply of pressure to the cylinder 19. The valves s3 and a l are provided with the plugs 45 and as and exhaust ports 47 and 28 respectively. The valve 43 is provided with the port d9 connected to one end of ne cylinder 19 by means of the pipe 50; and the valve i4: is provided with a port connected to the other end of the cylinder 19 by the pipe The plug 4-5 is provided with a cross passage or port 53 and the plug e6 with a similar port 54:; and the plugs are also provided with grooves 55 and 56 respectively. Pressure 1s supplied to the valves 48 and a l by means of the plpe 57 leadin to the ports 58 formed in the casings or the valves. The casing of each valve is provided with a port 59 which opens into the port 58 in each casing and into the cylinders at either end of the plugs l5 and L6. The plugs are prevented from coming iiush with the forward ends of the valve cas-- ings by means of the nipples 60 formed on the plugs. The rear ends of the cylinders are provided with port openings connected by a pipe 61 which leads to an exhaust valve 62' operated by the handle 68. 'ljhe plug a5 is provided with a stem 64 which projects through the rear end of the valve casing and the plug d6 is provided wlth a similar stem. A pipe 50 connects one end of the cylinder 16 with the pipe 50 and the pipe 52 connects the other end of the cyl inder 1G to the pipe in the position indicated in Fig. 4:, pressure is exhausting from the forward end of the cylinder 16 through the pipe 50, pipe 50, groove 55 and exhaust port 4:7 in the valve casing 43; and pressure is exhausting from the forward end of the cylinder 19 through the pipe 50, groove 55, and port 47. The plugl5 and 4:6 are in balance inasmuch as the pressure flowing into the valve from the pipe 57 and ports 58 flows to either end of the plugs through the ports Assuming that the lever (38 is pressed downwardly and the valve 62 opened, the pressure at the rear end of the plugs and do is exhausted through the pipe 61 to the atmosphere and the pressure at the forward end of the plugs causes them to move rearwardly to the position indicated in Fig. 5, at which time the passage 53 establishes communication between the port 58 in the valve casing d3 and the port t9, the pressure flowing from said port through the pipe 50 to the rear end of the cylinder and through the pipe 50 to the rear end of the cylinder 16, causing the piston 20 to be moved forwardly and the shears 17 to close. The port 58 in the valve casing it is closed and the groove 56 in the plug d6 establishes communication between the exhaust port 48 and the pipe 52, the pressure in the forward end of the cylinder 16 and in the forward end of the cylinder 19 exhausting through the pipes 52 and 52, groove 56, and exhaust port d8.

In the position illustrated in Fig. 5, the piston rod 20 has not reached its extreme forward position and is still moving forwardly. The abutment 42 has come into engagement with the forward rod 39 and as the forward movement of the piston rod 20 continues, the abutment will move the rod forwardly and the cross piece ll carried on the rod 38 will take against the stems 8% on the plugs a5 and d6, moving the said plugs to forward position as shown in Fig. l. in this position, the passage 5 iestablishes communication between the port 58 of the valve 44: and the pipe 52, and pressures from the pipe 57 flows through pipe to the forward end of the cylinder 19 and through pipe 52 to the forward end of the cylinder 16, thus causing the piston rod 20 to move to rear position and the shears to open. The plug 3:2 of the valve 30, however, will be shifted so as to uncover the port 35 and establish communication between port 33 and the exhaust port 3- Pressur is supplied to the valve 30 by the pipe 6* and the pressure will flow through the port and pipe 37 to the upper end of the cylinder 13, causing the plunger to move downwardly, the pressure in the lower end of the cylinder 13 exhausting through the pipe 86, port and port 34E. As the rearward movement of the rod 20 continues, the abutment 42 takes against the rear rod 39 and the rod 38 and plug 32 are shifted to the position shown in Fig. l and the plunger is elevated or retracted from the mold. The parts now remain in the position shown in Fl g. 1 until the operator again opens the exhaust valve 62 which causes the plugs 45 and d6 to move rearwardly.

After the completion of the forward movetil Mar

ment of the piston rod 20, when are in position for the plunger to come down and form a blank, at which time the rod 20 is being returned to rear position for the advancement of the table to the next station, it is desirable to have the table locked. The locking means comprises the vertical rod 66 adapted to engage holes 67 in cams secured to the bottom face of the table and normally held in upper or looking position by means of the spring 68; the arm 69 which is pivoted at one end to a standard 70 for rocking movement about a horizontal axis and to which the rod 66 is pivoted; a cam lever 71 is pivotally mounted in a standard 72; and an abutment 73 formed on the rear plate'22 carried by the rods 20 and 21. lVhen the rod 20 moves forwardly the cam lever is released and the spring 68 moves the rod 66 upwardly to lock the table, and when the rod 20 returns to rear position, the abutment 7 3 engages the cam lever, forcing it downwardly. lhe end of the lever engages the arm 69 and depresses it which in turn moves the rod 66 downwardly to release the table. It is ad vantageous to have the table start quickly when it moves from station to station and slow up at the end of each arc movement. To accomplish this, I provide a plurality of tapering cam pieces 74L on the bottom face of the table in position to be engaged by the rod 66. After the table has started and traveled a short distance, the rod engages a cam piece and the movement of the table is retarded the rod tightly against the cam piece, ofiering a frictional resistance to the turning of the table which increases toward the end of the arc movement of the table.

Briefly stated, the operation is as follows. The gatherer gathers a quantityof glass on a pontil and places it in positlon over a mold and, while doing so, depresses the handle 63,- the plugs 45 and 46 shift, causing the rod advance the table one station, and also causing the shears to close, cutting off the glass from the pontil; the abutment 42 shifts the valve 30 when the rod 20 reaches forward position, and the plunger 11 comes down and forms the blank, the table in the meantime being locked by the rod 66; the shifting of the valve 30 also causes the cross piece $1 to move the plugs 45 and 46 to initial position, which results in the opening of the shears and the return of the rod 20 to rear table, the plunger remaining in the mold during this movement; the rod :20 when returning to rear position shifts the valve 30 to initial position, causing the plunger 11 to be retracted and effecting the release of the table. The machine is now ready for another operation.

the parts inasmuch as the spring 68 presses 20 to move forwardly to position to get'a new grip on the The arrangement is simple and the valvular devices are automatically but positively actuated so that'regnlarity and effectiveness in operation is obtained.
